Question

what is the product of (2a) and (3a^2+2a-3)​

Answer 1

Answer:

Concept :

If ∣x∣= u  then = ± u

Given :

| 2a − 3∣= 3 a + 2

Using the given concept :

2 a − 3 = ± ( 3 a + 2 )

case (i):

2a − 3 = 3a + 2

−2 − 3 = 3a − 2a

⟹ a = 51

But a=-5 does not satisfy the given equation 

∴The solution is a=51

Answer 2

Given :

Two terms $2a$ and $3a^{2} +2a-3$.

To find :

The product of the terms.

Step-by-step explanation:

• The product of two terms can be found by following these steps.

• The 1st term must be multiplied with all the terms of 2nd.

       $(2a)(3a^{2} +2a-3)$

• Take $2a$ inside

      $(2a)(3a^{2} )+(2a)(2a)-3(2a)$

• Remove the brackets

      $6a^{3} +4a^{2} -6a$

Final answer :

The product of $2a$ and $3a^{2} +2a-3$ is $6a^{3} +4a^{2} -6a$.
